Experimental and thermodynamic investigations in the Ti‐Si‐C system

Abstract

The Si‐rich part of the 1100°C isothermal section and the isopleths at 5, 10 and 15 at.% C in the Ti‐Si‐C system were determined by means of DTA and XRD techniques. Two ternary eutectic reaction temperatures (1330°C for LSi+SiC+TiSi2 and 1485°C for LTiSi+TiSi2+Ti5Si3Cx) and three transition reaction temperatures (1485°C for L+Ti5Si3CxTi3SiC → 2+TiSi2, 1473°C for L+Ti3SiC2TiSi2+SiC, and 1341°C for L+TiCbcc‐(Ti)+Ti5Si3Cx) were observed. The decomposition temperature of the ternary compound Ti3SiC2 was determined by using a Pirani technique. By considering the experimental results from the present work and literature data, a consistent thermodynamic data set for the Ti‐Si‐C system was obtained.

EXPERIMENTAL STUDIES AND THERMODYNAMIC CALCULATIONS OF STRUCTURAL AND PHASE COMPOSITION FOR Ti–Si–C SYSTEM AT HEAT TREATMENT

“…Для описания трехкомпонентной системы Ti-Si-C была использована термодинамическая оценка системы, выполненная в работах [15,16]. Набор параметров, предложенный в этих работах, наиболее полно учитывает все имеющиеся данные по системе Ti-Si-C и не только базируется на данных SGTE для чистых элементов [13], но и применяет описания для систем Ti-C, Si-C и Ti-Si, предложенные в работах [11,12,14].…”

The Methods of Preparation of Ti-Ni-X Alloys and Their Forming

“…1b (Du & Schuster, 1998) it is possible to see more detailed information on the isothermal section (at 1500°C-temperature recommended for melting of Ni-Ti based alloys) of the Ni-Ti-C ternary system. The composition in this system is given in atomic %.…”
